Abstract: 1,190,248. Upward flow bed filters. V. J. G. HARDING. I Dec., 1967 [4 Jan., 1967; 31 July, 1967], No. 54903/67. Headings B1D and B1T. An upward flow filter comprises a bed of particulate material of height H when quiescent, a retainer screen 2 defining the top of the filter chamber, (a) valve-controlled inlet(s) R, W for raw fluid and wash fluid, a filtrate outlet F above screen 2, and a valve-controlled wash fluid outlet W' opening into the chamber at 4 at a height # 1.5H but below the screen 2. As described, raw fluid forced in at R raises part of the bed and compacts it as at B against screen 2; this forms the filter element. After filtration, layer B collapses on removing the pressure; this may be assisted by fluid jets (not shown) and fluid from these jets leaves through conduit 5. Wash fluid is then introduced at W, which fluidises the bed to a height of about 1.5H Fig. 1 (not shown), and ultrasonic agitation may be used; thus dirty fluid is expelled and this washing cycle is repeated 8 or 10 times to clean the filter bed. Simultaneously, auxiliary cleaning fluid may be flushed down through screen 2. A supporting screen 3, similar to 2, may be provided. Applications relate to filtering liquids or gases; in the latter case the medium used may be sawdust or plastics particles.

Abstract: 1399557 Making rivets integral with metal sheets VEREINIGTE ALUMINIUM-WERKE AG 20 Dec 1972 [24 Dec 1971] 58811/72 Headings B3A and B3Q A method of producing a tubular rivet integral with a metal sheet comprises forming a head portion of the rivet and an annular groove 4 around the head portion by stretch-forming using a punch and die, and applying pressure to the annular groove using a punch and die to form the rivet without further shaping of the head portion. In a first operation a bulge 3 is formed by a punch 1 of a bottom tool 2, the bulge having a diameter approximating that of the finished rivet. The groove 4 is then formed by a die 5. In a second operation, Fig. 2 (not shown), the groove is pressed flat and the resultant overflowing material, having been made available by the formation of the annular groove, is used to form the tubular rivet using a punch whose shape corresponds to that used in the first operation. Riveting of a gripping tongue to the surface of the sheet may then be effected by upsetting the rivet head to form a tear-open lid for a can containing material in liquid, paste or solid form.
